mcb: Use DEFINE_RES_MEM() helper macro and fix the end address
Use DEFINE_RES_MEM() to save a couple of lines of code, which makes the code a bit shorter and easier to read. The start address does not need to appear twice. By the way, the value of '.end' should be "start + size - 1". So the previous writing should have omitted subtracted 1. Fixes: acf5e051ac44 ("MCB: add support for SC31 to mcb-lpc") Fixes: 73edc8f7ccef ("mcb: Added support for LPC or non PCI based MCB carrier") Signed-off-by: Zhen Lei <thunder.leizhen@huawei.com> Link: https://lore.kernel.org/r/20210616073030.834-2-thunder.leizhen@huawei.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
